The only 'xt-type machine I have kept since the "old days" when such things
were common, is a "Challenger" motherboard (made ??? but sold through an
outfit in Boston) which was a 10MHz '186 as the processor in the 'XT
architecture. It had some 16-bit slots, though I never checked them out for
functionality, since there were few devices suitable for that.
Since the integrated peripherals could be relocated to an "out of the way"
location that was almost the first thing that happened in the ROM code.
I've held onto one just in case I ever needed to develop something for a
'186 again. That and the '188 and the NEC V-40 and V-50 were my favorites
of the time. I liked those built-in memory selects that allowed you to
build a system with almost no glue logic.
